* Crabeater seals (*Lobodon carcinophagus*): As their name suggests, crabeater seals primarily feed on krill, and are able to consume large quantities of it thanks to their specialised teeth. They are one of the most abundant seal species in the world, with an estimated population of around 15 million.
* Leopard seals (*Hydrurga leptonyx*): These powerful predators are known for their aggressive behaviour and are often seen hunting penguins, seals, and other seabirds. They are also able to dive to depths of over 1,500 metres, making them one of the deepest diving mammals.
* Ross seals (*Ommatophoca rossi*): Ross seals are found in the Ross Sea and are well-adapted to the cold temperatures, with a thick layer of blubber and a high tolerance for cold water. They feed primarily on squid and fish, and are known for their distinctive white markings around their eyes.
* Antarctic fur seals (*Arctocephalus gazella*): These seals are found on the Antarctic Peninsula and South Georgia, and are known for their thick, dark fur. They feed primarily on fish and krill, and are known for their playful behaviour and acrobatic displays.
* Southern elephant seals (*Mirounga leonina*): Southern elephant seals are the largest seals in the world, with males reaching weights of up to 4,000 kilograms. They are found on the Antarctic Peninsula and South Georgia, and feed primarily on squid, fish, and krill.
